Is there any information that BMW is working to upgrade this part, or are they content just to replace the suckers when they fail?

The HPFP is related to the N54 engine, the 335i's experienced the problems first, then the 135i's. I'd assume they'd have taken steps to address this with newer cars such as the X6, but you never know.
